As I see that I can view the labour market in other countries that I'm visiting, so I assume could get a job working in one of them.

But the wages are displayed in their local currency, and so I don't know if that's more or less than my home currency, as I can't find a way to compare the amount of $NZ for a gold bar vs $x for a gold bar.

Or are all currencies the same? and they just change the letters afterwards to make it prettier for players? (In which case, Chile is paying almost 2x the wage I can get in NZ lol)

There used to be an exchange rate, then the admins screwed up the game on purpose so they could get more Euros and Dollars for fake money, so currenty exchange is worthless except for exchanging gold....
